<p>Default: <code class="docutils literal notranslate"><span class="pre">[]</span></code> (Empty list)</p>
<p>A list of strings representing the host/domain names that this Django site can

seemingly-safe web server configurations.</p>
<p>Values in this list can be fully qualified names (e.g. <code class="docutils literal notranslate"><span class="pre">'www.example.com'</span></code>),
in which case they will be matched against the request’s <code class="docutils literal notranslate"><span class="pre">Host</span></code> header
exactly (case-insensitive, not including port). A value beginning with a period
can be used as a subdomain wildcard: <code class="docutils literal notranslate"><span class="pre">'.example.com'</span></code> will match
<code class="docutils literal notranslate"><span class="pre">example.com</span></code>, <code class="docutils literal notranslate"><span class="pre">www.example.com</span></code>, and any other subdomain of
<code class="docutils literal notranslate"><span class="pre">example.com</span></code>. A value of <code class="docutils literal notranslate"><span class="pre">'*'</span></code> will match anything; in this case you are
responsible to provide your own validation of the <code class="docutils literal notranslate"><span class="pre">Host</span></code> header (perhaps in a
middleware; if so this middleware must be listed first in
<a class="reference internal" href="#std:setting-MIDDLEWARE"><code class="xref std std-setting docutils literal notranslate"><span class="pre">MIDDLEWARE</span></code></a>).</p>
<p>Django also allows the <a class="reference external" href="https://en.wikipedia.org/wiki/Fully_qualified_domain_name">fully qualified domain name (FQDN)</a> of any entries.
Some browsers include a trailing dot in the <code class="docutils literal notranslate"><span class="pre">Host</span></code> header which Django
strips when performing host validation.</p>
<p>If the <code class="docutils literal notranslate"><span class="pre">Host</span></code> header (or <code class="docutils literal notranslate"><span class="pre">X-Forwarded-Host</span></code> if
<a class="reference internal" href="#std:setting-USE_X_FORWARDED_HOST"><code class="xref std std-setting docutils literal notranslate"><span class="pre">USE_X_FORWARDED_HOST</span></code></a> is enabled) does not match any value in this

is validated against <code class="docutils literal notranslate"><span class="pre">['localhost',</span> <span class="pre">'127.0.0.1',</span> <span class="pre">'[::1]']</span></code>.</p>
<p><code class="docutils literal notranslate"><span class="pre">ALLOWED_HOSTS</span></code> is also <a class="reference internal" href="../topics/testing/advanced.html#topics-testing-advanced-multiple-hosts"><span class="std std-ref">checked when running tests</span></a>.</p>
<p>This validation only applies via <a class="reference internal" href="request-response.html#django.http.HttpRequest.get_host" title="django.http.HttpRequest.get_host"><code class="xref py py-meth docutils literal notranslate"><span class="pre">get_host()</span></code></a>;
if your code accesses the <code class="docutils literal notranslate"><span class="pre">Host</span></code> header directly from <code class="docutils literal notranslate"><span class="pre">request.META</span></code> you
are bypassing this security protection.</p>

<p>The age of CSRF cookies, in seconds.</p>
<p>The reason for setting a long-lived expiration time is to avoid problems in
the case of a user closing a browser or bookmarking a page and then loading
that page from a browser cache. Without persistent cookies, the form submission
would fail in this case.</p>
<p>Some browsers (specifically Internet Explorer) can disallow the use of
persistent cookies or can have the indexes to the cookie jar corrupted on disk,
thereby causing CSRF protection checks to (sometimes intermittently) fail.

<p>The domain to be used when setting the CSRF cookie.  This can be useful for

<p>Designating the CSRF cookie as <code class="docutils literal notranslate"><span class="pre">HttpOnly</span></code> doesn’t offer any practical
protection because CSRF is only to protect against cross-domain attacks. If an

a much bigger hole than CSRF.)</p>
<p>Although the setting offers little practical benefit, it’s sometimes required

request, your JavaScript must pull the value from a hidden CSRF token form
input on the page instead of from the cookie.</p>

<p>Default: <code class="docutils literal notranslate"><span class="pre">False</span></code></p>
<p>A boolean that turns on/off debug mode.</p>
<p>Never deploy a site into production with <a class="reference internal" href="#std:setting-DEBUG"><code class="xref std std-setting docutils literal notranslate"><span class="pre">DEBUG</span></code></a> turned on.</p>
<p>Did you catch that? NEVER deploy a site into production with <a class="reference internal" href="#std:setting-DEBUG"><code class="xref std std-setting docutils literal notranslate"><span class="pre">DEBUG</span></code></a>
turned on.</p>
<p>One of the main features of debug mode is the display of detailed error pages.
If your app raises an exception when <a class="reference internal" href="#std:setting-DEBUG"><code class="xref std std-setting docutils literal notranslate"><span class="pre">DEBUG</span></code></a> is <code class="docutils literal notranslate"><span class="pre">True</span></code>, Django will
display a detailed traceback, including a lot of metadata about your
environment, such as all the currently defined Django settings (from
<code class="docutils literal notranslate"><span class="pre">settings.py</span></code>).</p>
<p>As a security measure, Django will <em>not</em> include settings that might be
sensitive, such as <a class="reference internal" href="#std:setting-SECRET_KEY"><code class="xref std std-setting docutils literal notranslate"><span class="pre">SECRET_KEY</span></code></a>. Specifically, it will exclude any
setting whose name includes any of the following:</p>
<ul class="simple">
<li><code class="docutils literal notranslate"><span class="pre">'API'</span></code></li>
<li><code class="docutils literal notranslate"><span class="pre">'KEY'</span></code></li>
<li><code class="docutils literal notranslate"><span class="pre">'PASS'</span></code></li>
<li><code class="docutils literal notranslate"><span class="pre">'SECRET'</span></code></li>
<li><code class="docutils literal notranslate"><span class="pre">'SIGNATURE'</span></code></li>
<li><code class="docutils literal notranslate"><span class="pre">'TOKEN'</span></code></li>
</ul>
<p>Note that these are <em>partial</em> matches. <code class="docutils literal notranslate"><span class="pre">'PASS'</span></code> will also match PASSWORD,
just as <code class="docutils literal notranslate"><span class="pre">'TOKEN'</span></code> will also match TOKENIZED and so on.</p>
<p>Still, note that there are always going to be sections of your debug output
that are inappropriate for public consumption. File paths, configuration
options and the like all give attackers extra information about your server.</p>
<p>It is also important to remember that when running with <a class="reference internal" href="#std:setting-DEBUG"><code class="xref std std-setting docutils literal notranslate"><span class="pre">DEBUG</span></code></a>
turned on, Django will remember every SQL query it executes. This is useful
when you’re debugging, but it’ll rapidly consume memory on a production server.</p>
<p>Finally, if <a class="reference internal" href="#std:setting-DEBUG"><code class="xref std std-setting docutils literal notranslate"><span class="pre">DEBUG</span></code></a> is <code class="docutils literal notranslate"><span class="pre">False</span></code>, you also need to properly set
the <a class="reference internal" href="#std:setting-ALLOWED_HOSTS"><code class="xref std std-setting docutils literal notranslate"><span class="pre">ALLOWED_HOSTS</span></code></a> setting. Failing to do so will result in all
requests being returned as “Bad Request (400)”.</p>

skipped and exceptions propagate upwards.</p>
<p>This can be useful for some test setups. It shouldn’t be used on a live site
unless you want your web server (instead of Django) to generate “Internal
Server Error” responses. In that case, make sure your server doesn’t show the
stack trace or other sensitive information in the response.</p>

<p>Default: <code class="docutils literal notranslate"><span class="pre">{}</span></code> (Empty dictionary)</p>
<p>A dictionary specifying the package where migration modules can be found on a
per-app basis. The default value of this setting is an empty dictionary, but
the default package name for migration modules is <code class="docutils literal notranslate"><span class="pre">migrations</span></code>.</p>
<p>Example:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="p">{</span><span class="s1">&#39;blog&#39;</span><span class="p">:</span> <span class="s1">&#39;blog.db_migrations&#39;</span><span class="p">}</span>
</pre></div>
</div>
<p>In this case, migrations pertaining to the <code class="docutils literal notranslate"><span class="pre">blog</span></code> app will be contained in
the <code class="docutils literal notranslate"><span class="pre">blog.db_migrations</span></code> package.</p>
<p>If you provide the <code class="docutils literal notranslate"><span class="pre">app_label</span></code> argument, <a class="reference internal" href="django-admin.html#django-admin-makemigrations"><code class="xref std std-djadmin docutils literal notranslate"><span class="pre">makemigrations</span></code></a> will
automatically create the package if it doesn’t already exist.</p>
<p>When you supply <code class="docutils literal notranslate"><span class="pre">None</span></code> as a value for an app, Django will consider the app as
an app without migrations regardless of an existing <code class="docutils literal notranslate"><span class="pre">migrations</span></code> submodule.
This can be used, for example, in a test settings file to skip migrations while
testing (tables will still be created for the apps’ models). If this is used in
your general project settings, remember to use the <a class="reference internal" href="django-admin.html#cmdoption-migrate-run-syncdb"><code class="xref std std-option docutils literal notranslate"><span class="pre">migrate</span>

<p>The default formatting to use for date fields on Django admin change-list
pages – and, possibly, by other parts of the system – in cases when only the
month and day are displayed.</p>
<p>For example, when a Django admin change-list page is being filtered by a date
drilldown, the header for a given day displays the day and month. Different
locales have different formats. For example, U.S. English would say
“January 1,” whereas Spanish might say “1 Enero.”</p>

<p>Default: <code class="docutils literal notranslate"><span class="pre">0</span></code></p>
<p>Number of digits grouped together on the integer part of a number.</p>
<p>Common use is to display a thousand separator. If this setting is <code class="docutils literal notranslate"><span class="pre">0</span></code>, then

<code class="docutils literal notranslate"><span class="pre">en_IN</span></code>. For this case, you can provide a sequence with the number of digit
group sizes to be applied. The first number defines the size of the group
preceding the decimal delimiter, and each number that follows defines the size
of preceding groups. If the sequence is terminated with <code class="docutils literal notranslate"><span class="pre">-1</span></code>, no further
grouping is performed. If the sequence terminates with a <code class="docutils literal notranslate"><span class="pre">0</span></code>, the last group

<p>Default: <code class="docutils literal notranslate"><span class="pre">None</span></code></p>
<p>A tuple representing a HTTP header/value combination that signifies a request
is secure. This controls the behavior of the request object’s <code class="docutils literal notranslate"><span class="pre">is_secure()</span></code>
method.</p>
<p>This takes some explanation. By default, <code class="docutils literal notranslate"><span class="pre">is_secure()</span></code> is able to determine
whether a request is secure by looking at whether the requested URL uses
“<a class="reference external" href="https://">https://</a>”. This is important for Django’s CSRF protection, and may be used
by your own code or third-party apps.</p>
<p>If your Django app is behind a proxy, though, the proxy may be “swallowing” the
fact that a request is HTTPS, using a non-HTTPS connection between the proxy
and Django. In this case, <code class="docutils literal notranslate"><span class="pre">is_secure()</span></code> would always return <code class="docutils literal notranslate"><span class="pre">False</span></code> – even
for requests that were made via HTTPS by the end user.</p>
<p>In this situation, you’ll want to configure your proxy to set a custom HTTP
header that tells Django whether the request came in via HTTPS, and you’ll want
to set <code class="docutils literal notranslate"><span class="pre">SECURE_PROXY_SSL_HEADER</span></code> so that Django knows what header to look
for.</p>
<p>You’ll need to set a tuple with two elements – the name of the header to look
for and the required value. For example:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">SECURE_PROXY_SSL_HEADER</span> <span class="o">=</span> <span class="p">(</span><span class="s1">&#39;HTTP_X_FORWARDED_PROTO&#39;</span><span class="p">,</span> <span class="s1">&#39;https&#39;</span><span class="p">)</span>
</pre></div>
</div>
<p>Here, we’re telling Django that we trust the <code class="docutils literal notranslate"><span class="pre">X-Forwarded-Proto</span></code> header
that comes from our proxy, and any time its value is <code class="docutils literal notranslate"><span class="pre">'https'</span></code>, then the
request is guaranteed to be secure (i.e., it originally came in via HTTPS).

<p><a class="reference external" href="https://www.owasp.org/index.php/HTTPOnly">HTTPOnly</a> is a flag included in a Set-Cookie HTTP response header. It
is not part of the <span class="target" id="index-1"></span><a class="rfc reference external" href="https://tools.ietf.org/html/rfc2109.html"><strong>RFC 2109</strong></a> standard for cookies, and it isn’t honored
